Jean Jacques Rousseau (plato.standford.edu)
Jean-Jacques Rousseau remains an important figure in the history of philosophy, both because of his contributions to political philosophy and moral psychology and on account of his influence on later thinkers. Rousseau’s own view of most philosophy and philosophers was firmly negative, seeing them as post-hoc rationalizers of self-interest, as apologists for various forms of tyranny, and as playing a role in the alienation of the modern individual from humanity’s natural impulse to compassion. The concern that dominates Rousseau’s work is to find a way of preserving human freedom in a world where people are increasingly dependent on one another to satisfy their needs.- Neuron (Wikipedia)
Within a nervous system, a neuron, neurone, or nerve cell is an electrically excitable cell that fires electric signals called action potentials across a neural network. Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the synaptic gap.
